[Koha-devel] help with nomenclature

[Paul]

Does anyone have a "cheat sheet" covering the nomenclature of fields, 
strings, descriptions, etc used in the various components of Koha? (mysql, 
perl, inc, tt etc)

For example, I would like to add to a "moredetails.pl" prequest a couple 
more editing possibilities (just like "Lost", "Damaged" and "Withdrawn") 
such as "Shelving location" (952$c) and 952$g that we use for Fair Market 
Value.

As an example of trying to trace a variable (from additem.pl), the raw data 
gets transformed/added to during various loops from 952$c and tracing 
"shelving" from:

<div id="subfield952c175402" class="subfield_line" style="">
<label>
c -
<span id="error13" title="Shelving location">Shelving location</span>
</label>
<select id="tag_952_subfield_c_166742" class="input_marceditor" size="1" 
tabindex="1" name="field_value">
<input type="hidden" value="952" name="tag">
<input type="hidden" value="c" name="subfield">
<input type="hidden" value="0" name="mandatory">
</div>

which poses as many questions as it answers -- and I'd like to proceed as 
efficiently as possible.

The various online manuals etc do not appear to have a nomenclature / logic 
flow chart but I am hoping that one of you may have something ready made 
along these lines

I'd also appreciate pointers to the origins of subfield952c175402, error13, 
tag_952_subfield_c_166742, etc - I'm guessing I could cause a minor 
disaster in the sql.

Thanks and best regards,
Paul
